What about Debian itself? Are there plans to integrate netplan.io and replace
/etc/network/interfaces like has been done in Ubuntu? I can see that netplan.io is included in Debian Buster. Will it be installed by default?
Even if the default switched to systemd networking or Network Manager, there’s another obstacle to the use of netplan.io in the default installation, which is that it requires Python. (Its use by default in Ubuntu is less surprising since netplan.io is developed by Canonical.)
